Theres lots of purposes of using rust in the first place. Some people want the performance. Some people want the safety guarantees and the checking the compiler does for correctness. Some people want the expressive type system (and combined with the above, the ability to encode constraints into data types). I don't think that people who choose based on the third but don't need super tight performance are using it wrong, they just have a different set of priorities than those that are using it for very high performance.
